摘要： The invention relates to a continuous steam generator (1) wherein an evaporator throughflow heating surface (8) is disposed in a gas duct (6) which can be cross flown in an approximately vertical manner in a heating gas device (y), said evaporator throughflow heating surface comprising a plurality of parallel connected steam generating pipes (12) enabling a flow medium (W) to flow through, also enabling particularly high operating stability and security during the supply of the flow medium (W) having a comparatively high mass flow density. The inventive evaporator throughflow heating surface (8) comprises a heating surface segment (20) which can be cross-flown by the flow medium (W) in an opposite direction to the gas duct (6), the flow medium side exit (16) is positioned in such a manner that it can be seen in the heating direction of the gas (y) such that the saturated steam generator which is adjusted during operation according to pressure in the evaporator throughflow heating surface (8) deviates by less than a maximum predetermined amount from the heating gas temperature prevailing during operation at the position of the exit (16) of the heating surface segment (20).

摘要： Disclosed is a steam generator (1) in which a continuous evaporating heating area (8) is disposed within a heating gas duct (6) that is penetrated in a nearly horizontal direction (x) by a heating gas. Said continuous evaporating heating area (8) comprises a number of steam-generating pipes (12) that are connected in parallel and are penetrated by a flowing medium (D, W) and is configured such that a steam-generating pipe which is heated more than another steam-generating pipe (12) of the same continuous evaporating heating area (8) has a higher throughput of the flowing medium (W) than said other steam-generating pipe (12). The aim of the invention is to create a steam generator which provides a particularly high degree of stability of flow during operation of the continuous evaporating heating area (8) while keeping the structural complexity and design comparatively simple. Said aim is achieved by means of a discharge collector (20) which is mounted downstream of the steam-generating pipes (12) of the continuous evaporating heating area (8) on the side of the flowing medium, and the longitudinal axis of which is located essentially parallel to the direction (x) of the heating gas.

摘要： The invention relates to a steam generator (2) with a denitrification device for heating gas (G) and a combustion chamber (4). The denitrification device (54) for heating gas (G) is connected downstream of said combustion chamber on the heating gas side by a horizontal gas duct (6) and a vertical gas duct (8). The invention aims to provide a steam generator which requires, in particular, a minimum amount of space and which guarantees a particularly reliable denitrification of the heating gases (G) of the fossil fuel (B). To this end, a number of burners (70) are located at the height of the horizontal gas duct (6). In addition, the vertical gas duct (8) is configured for an approximately vertical flow of the heating gas (G) from the bottom upwards and the denitrification device (54) for heating gas (G) is configured for an approximately vertical flow of the heating gas (G) from the top downwards.

摘要： The invention concerns a continuous-flow steam generator (2) with a gas flue made up of evaporation tubes (10) welded together with fins (13) to form a gastight seal. The tubes (10) are connected in parallel to allow a fluid to flow through them, have on their inside surface a structure designed to produce strong turbulence in the fluid flowing through them and are wound in an essentially spiral coil in the firing area (V) of the flue. In order to be able to operate a steam generator (2) of this kind under low loads of for instance about 20 % of the design load without causing excessive thermal stresses, the invention calls for the evaporation tubes (10) to be designed so that the geodesic losses in pressure in the fluid flowing through the tubes are at least 0.5 times the losses in pressure due to friction.

摘要： A process is disclosed for starting a flow steam generator (1) with a combustion chamber (6) having a plurality of burners (5) for a fossil fuel (B) and a gas-tight external wall (2) made of at least approximately vertical evaporator pipes (4) through which feed water flows upwards. In order to avoid starting losses, the water level (H) in the evaporator pipes (4) and the ratio between fuel flow and feed water flow are set in such a way that the water (S) completely evaporates when flowing through the evaporator pipes (4), so that no more water is available at the evaporator outlet (10). For that purpose, a starting system (84) is used having regulating means (66) for regulating the water level (H) in the evaporator (4), as well as the ratio between fuel flow and feed water flow.

摘要： The invention relates to a fossil fuel fired steam generator (2) which has a combustion chamber (4) which is designed for an approximately horizontal main direction of flow (26) of the fuel gas (G). On the heating gas side a vertical gas extractor (8) is mounted downstream of a horizontal gas extractor (6). The external walls (9) of the combustion chamber (4) are formed by evaporator tubes (10). The aim of the invention is to keep temperature differences between adjacent evaporator tubes (10) of the combustion chamber (4) to a minimum at all load states of the steam generator (2). To this end, a first group (18) and a second group (20) of the evaporator tubes (10) can be impinged in parallel with a flow medium (S), said first group (18) being mounted in series with the second group (20) of the evaporator tubes (10).
